Description
The THDB Series combines accurate timing circuitry with high
power, solid-state switching. It can switch motors, lamps, and
heaters directly without a contactor. You can reduce labor,
component cost, and increase reliability with these small,
easy-to-use, timers.
Operation (Delay-on-Break)
Input voltage must be applied before and during timing. Upon
closure of the initiate switch, the output energizes. The time
delay begins when the initiate switch is opened. The output
remains energized during timing. At the end of the time delay,
the output de-energizes. The output energizes if the initiate
switch is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets the time
delay. Loss of input voltage resets the time delay and output.
